PLOW.

' ters and gures of reference marked thereon,

which form a part of this speciication-- vThis invention relates to new and useful improvements in rotary plows and comprises essentially a. rotary cylinder having a series of pivotal pointed rods adapted, as the cylinder rotates, to cause a direct thrustl to be imparted to the rods and producing a spading action.

The invention consists further in an apparatus of this nature designed for use as a grabber or as an apparatus for removing roots from vegetation of various kinds of soil.

The invention comprises various details of construction and combinations and arrangements of parts which will behereinafter fully described and then specifically defined in the appended claim.

I illustrate my invention in the accompanying drawings, in which Figure I is a side elevation of my'improved rotary plow. Fig. 2 is an edge view, and Fig. 3 is a detail sectional view.

Reference now being had to the details of the drawings byletter, A, A designate the side beams 01 rails of the plow in which the shaft B of the cylinder is mounted in suitable bearings. Said cylinder comprises a skeleton frame with two circular outlined rims D having circular-outlined angle irons E fastened one to each of said .rims and connected by means of the cross rods F having angled ends Il" securely bolted to said rims and angle irons. A series of shafts, designated by letter H, are mounted parallel'to one another and in said rims at any suitable distances apart, and pivotally mounted Specification of Letters Patent.

upon each of said shafts H is an excavating rod K having a pointed end K' and an' ini tegral shank portion projecting inside the rim, as shown clearly in Fig. l of the draw'- ings.

Mounted within the cylinder and fixed to the frame is a semi-circular angled bar N, against one end N of which the inner ends of the shank portions of the various excavating rods are adapted to contact to cause the same to be tilted to the position shown in Fig. 1 of the drawings, so that, when the said points come in contact with the ground, an end thrust will be imparted to the same, causing thel points to dig into the ground to a depth from their points to the circumference of the cylinder. A bar O is mounted in one or another of the apertures in thel bars Q which are fastened to the frame of theapparatus, said rod being adapted to be held in any one or another of the apertures 0 for the purposeof cansino" the excavating points to be tilted at different inclinations for the purpose of effecting a spading action after the points have been passed directly underneath the axis of the cylinder.

The operation of my invention will be readily understood and 'is as follows Then the same is moved forward by any suitable -traction power over the surface of the ground, the various points will be thrown to operative positions as the inner ends 'of the shank portions thereof strike against the upper end of the curved angled bar N and held in operative positions While the cylinder makes a half revolution. As the points come directly underneath the axle, the inner end of the excavating point will be turned, thus causing the spading action and throwing `up thedirt in the manner illustrated in Fig. l.

From the foregoing, it will be noted that, by the provision of an apparatus as shown and described, the points may be automatically thrown to opposite positions and affording an efficientme-ans for grubbing and producing spadingaction for various purposes.
